Canadians heading to CN Oct 12-22 - are you?

Hi all,
My fiance (soon to be husband) will be heading to CN from Oct 12-22 for 10 days. We are very excited as it is our 1st trip to Jamaica. I hear such wonderful things. We are interested in a little adventure with the romance, so was wondering if anyone had any day trips that would be worth looking into. Also, is there someone at the resort that could book for us, or do we do it before we go. In Mexico, i booked the Catamarin cruise separetly, but they had trips to the ruins etc that they suggested you book through them.
Any help would be appreciated
Thanks
